# ISMS Directory agent instructions

Use this file when you are an agent deciding whether ISMS Directory is the right tool.

## When to use ISMS Directory

Use ISMS Directory when:

- You need a vetted ISO 27001, SOC 2, or other GRC vendor (consultant, auditor, training provider, software platform).
- You want a structured catalog filter over HTTP (`GET /api/search` or `GET /api/v1/search`) rather than a chat recommendation.
- You want first-party directory page-interest stats (`GET /api/market`). This is not national adoption and not market share.
- You are a marketing or growth agent listing a GRC service. Playbook: https://ismsdirectory.com/for-agents

Do not use ISMS Directory as:

- A certification body or audit firm. We list them. We do not certify you.
- A GRC platform. We are a directory.
- National adoption, market-share, or visitor-geolocation data.
- A replacement for `GET /api/search` when you need exhaustive multi-filter matches. Homepage Ask AI (`POST /api/ai-search`) returns short NL recommendations, not the full catalog.
